CIRCUIT BREAKER WITH DOUBLE BREAK CONTACTS AND NON-POLARITY SENSITIVE DESIGN

A circuit interrupter includes a first set of contacts connected in series with a second set of contacts, with both sets of contacts configured to open and close simultaneously. First and second arc extinguishers are associated with the first and second sets of contacts, respectively. A moveable permanent magnet moves as the sets of contacts simultaneously open and close, the moveable magnet generating a moveable magnetic field, a first stationary permanent magnet associated with the first arc extinguisher, the first stationary magnet generating a first stationary magnetic field, where the first stationary magnetic field and the moveable magnetic field are additive, and a second stationary permanent magnet associated with the second arc extinguisher, the second stationary magnet generating a second stationary magnetic field, where the second stationary magnetic field and the moveable magnetic field are also additive. L'invention concerne un interrupteur de circuit qui comprend un premier ensemble de contacts raccordés en série à un second ensemble de contacts, les deux ensembles de contacts étant configurés pour s'ouvrir et se fermer simultanément. Des premier et second dispositifs d'extinction d'arc sont associés aux premier et second ensembles de contacts, respectivement. Un aimant permanent mobile se déplace au fur et à mesure que les ensembles de contacts s'ouvrent et se ferment simultanément, l'aimant mobile générant un champ magnétique mobile, un premier aimant permanent fixe associé au premier dispositif d'extinction d'arc, le premier aimant fixe générant un premier champ magnétique fixe, le premier champ magnétique fixe et le champ magnétique mobile étant additifs, et un second aimant permanent fixe associé au second dispositif d'extinction d'arc, le second aimant fixe générant un second champ magnétique fixe, le second champ magnétique fixe et le champ magnétique mobile étant également additifs.
